And there came indeed to them their Messengers with clear proofs, but they were not such as to believe in that which they had rejected before. Thus Allah does seal up the hearts of the disbelievers (from each and every kind of religious guidance). 101 And We did not find for most of them any covenant; but indeed, We found most of them defiantly disobedient. 102 After the time of those people, We sent Moses with Our miracles to Pharaoh and his people, but they too rejected Our miracles. Consider, how terrible the end of the evil-doers is! 103 And Musa said: O Firon! surely I am an apostle from the Lord of the worlds: 104 Approved upon condition that I speak concerning Allah nothing but the truth. I come unto you (lords of Egypt) with a clear proof from your Lord. So let the Children of Israel go with me. 105 Said [Pharaoh]: "If thou hast come with a sign, produce it - if thou art a man of truth!" 106 Thereupon [Moses] threw down his staff, and lo! it was a serpent, plainly visible; 107 Then he drew out his hand, and it appeared luminous to all beholders. 108
